.PREV DISCUSSION... /issued 356 AM CDT Sun Apr 30 2017/

SHORT TERM...
(Today and Tonight)

Expect windy weather across the Big Country and breezy elsewhere
today due to strong pressure gradient on the back side of a storm
system and some vertical mixing. The winds will be from the
northwest at 25 to 35 mph with gusts to 40 mph across the Big
Country, and a Wind Advisory is in effect from Noon until 7 PM.
Expect speeds of 15 to 25 mph elsewhere across West Central Texas.
Temperatures will be cool this afternoon, with highs in the mid
60s to lower 70s.

The winds will rapidly decrease this evening. The combination of
clear skies, light winds and a dry airmass will lead to good
radiational cooling. Lows by Monday morning will be mainly in the
lower to mid 40s, with upper 30s possible in low lying areas and
river valleys.

LONG TERM...
(Monday through Saturday)

Upper low shifts into the Great Lakes on Monday, with west
northwest flow across the area. A weak cold front will slide into
the Big Country and keep temperatures a few degrees cooler along
and north of I-20. Elsewhere, nice warmup in store with readings
climbing into the mid and upper 80s. Another potent shortwave will
quickly drop into the Plains for Wednesday and Wednesday Night,
with another cold front moving through the area. Showers and
storms will develop, with best chances east and south of the area
where low level moisture will be a little deeper. Models have some
differences in how far west they develop the convection, but
certainly worth the 20% and 30% PoPs in the forecast. After highs
in the mid and upper 80s on Tuesday, highs will cool into the low
to mid 70s by Thursday behind the front.

The shortwave closes off and develops into an upper low over the
mid Mississippi Valley for the end of the week. Dry conditions for
West Central Texas and a gradual warming trend into the weekend.
